I did my brushing, flossing, scrapping my tongue plus checking my teeth with doctor but my breath is still bad.help me.

Bad breath: Despite your brushing your bad breath may come from a post nasal drip or possibly gastro esophageal, reflux.

Check GI: I would check with your family md and have him take a look at your tonsils.

Different cause: You assume that your halitosis is coming from your mouth. It may be due to your diet or acid reflux. See a gastroenterologist.
